To @ZZ wit-0m zit may concern,.-

Be it known that I, JOSEPH M. LAWRANGE, of New YWhatcom, in the countyofWhatcom and State of ii'v'ashington, have invented certain new anduseful Improvements in Self- Binders; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, referencefbeing had to-the accompanying drawings, whichform part of this specification,

My invention relates to improvements in self binders, and itconsists inthe construe tion and arrangement of parts which will be fully describedhereinafter and particularly referred to in the claims.

The object of my invention is to construct a self binder capable oftwisting a band out of the stem of the grain and then binding a bundlethereof with the twisted hand.

In the accompanying drawings: Figure l, is a perspective view of abinder which embodies my invention. Figs. 2 and 3, are side elevationsthereof looking in opposite directions. Fig. 4, is an 4end view lookingin the direction indicated by arrow in Fig. 2.v

longitudinal sectional view of the hollow shaft which is journaled inthe band twister frame.

Fig. 6, is a detached view of the band twist# ing clamps. Fig. 7, isadetached view ofthe lower end of the swinging crane and the adjacentends of the horizontal shaft, for turning the said crane in onedirection. Fig. 8, is a segmental view showing the. lever for moving theoperating shaft endwise.

A indicates a horizontal base frame inlow shaft is provided with twosprocket wheels F and G, the outer drivingchain F. passing around asprocket wheel H, which is secured rigidly to a short shaft I. InFig..8, I show a' lever a2 having an inner forked end extending betweenthe friction disks (Las one way Fig.v et, is a plan view of the same.Fig. 5, is a said collar is moved by the lever M.

-in which the same may be moved endwise. Rigidly secured to the outerend of this shaft I, is a wheel J provided with .a circular slot K, inwhich the lower bent end of a rod or pitman M extends the upper end ofsaid rod being attached to the outer end of a short lever M. the purposeof the slot K being to permit` the wheel J to make a portion of arevolution without affecting the collar U through the medium of thelever M,thus allowing the arms of the cradle (to be described presently)to remain quiet while receiving the bundle to be bound.

Journaled within the frame A is a vertical shaft N which carries at itslower end a pinion P, for apurpose to be fully described hereinafter.Secured to the upper end of this vertical shaft is a cradle frame Q,consisting of a series of U-shaped arms R, as shown. Extending inopposite directions from the center of this cradle frame are the arms S,between which the compression arms T, are pivoted intermediate theirends. The lower ends of these arms T are connected with a sliding collarU, through the medium of links V, and this collar is provided with acircular groove W into which the inner end of the aforesaid lever Mextends.V From this it will be seen that as the circular slotted wheel.I is revolved through the medium of the driving shaft and the sprocketchain which operatively connects the two, the inner ends of theleverMengaging the collarraises and lowers the same, thus causing the upperend of the said compression arms to move in or ont according to thedirection in which the These compression arms are provided at theirupperends with springprongs X, which receive the twisted band from the bandtwister, as will be fully described farther on.

A horizontal shaft Y is journaled in the frame A and preferably in aline with the short shaft carrying the Wheel .L and this shaft Y isprovided with a segmental cog wheel Z adjacent to the pinion upon thelower end of the said vertical shaft. This shaft Y carries a sprocketwheel ct, around which a sprocket chain b passes, and the opposite endof this said sprocket chain b passes around the other sprocket wheel Gupon the shaft before mentioned. At the opposite end of this in thevertical bar 3.

shaft Y is a vertical fralneB, which supports a swinging crane c, thelowerend of this said crane being provided with an inwardly extendingprojection d, with which a dog or projection e, upon the shaft Yengages, as the said shaft revolves for the purpose of turning the upperend of the said crane outward from over the cradle frame, for a purposewhich will appearfartheron. ThesaidshaftYatitsouter end outside of theframe A and adjacent to the lower end of the swinging crane is providedwith a wheel and this said wheelf, is provided with a series of cogs g,and separated therefrom a single cog h, and betweenthe said series ofcogs and the single cog, is an arm t', which engages the projecting endof a shaft j.

Thisshaft 7' carries at its outer end a pinion 7c,

.and at its inner end a drum l', the said shaft being journaled in thevertical portion of the said swinging crane. The upper end of this cranehasa bracket m, pivoted at its .inner end rthereto, the outer end of thesaid arm .car-ryinga combined twister and tucker for securing .the endsof the bands, which tucker will be fully kdescribed farther on.

Extending upward from the frame A intermediate its end and at oppositesides thereof are the standards o, which are provided with verticalopenings or slots p, through which a hollow shaft q, extends and inwhich the said shaftisjournaled. Extendingacross thefrarne Aand justabove it and under the hollow shaft q, is ashaft r, which carries at oneend a cog wheel s, Whichrests upon an inclined cog surface t, theopposite end of the said shaft being provided with a wheel u, whichrests upon an Yinclined track i), corresponding to the inclined cogtrack at the opposite end of the said frame A. The hollow shaft q isprovided with 4a pinion tu, which engages with the cog wheel upon .theshaft rr', and outside of the pinion w, is a sprocket wheel 1, aroundwhich a sprocket chain 6, passes. Outside of this pinion w and inside ofthe large sprocket wheel 1, isa vertical frame bar 2, in which the shafta" is journaled, and extending upward from the opposite end of the shafti', is a vertical bar 3, which is connected with the vertical bar 2, bymeans of a cross bar 4. One end ofthe hollow shaft q, while sliding inthe said vertical opening of the standards o is at the same timejournaled The hollow shaft q, is ,provided with an internal screw thread23, with which a nut or projection 24, upon `the, inner end of a rod 16,engages, so that as the said hollow shaft q, revolves the said shaft16,isy moved endwise. Connected to the outer endof this rod 16 is anupright standard 5, the lower end of the said standard sliding upon theshaft 7^. Connected to the upper end of the standard 5, is a claspconsisting of a movable jaw 14, and stationary jaw 13. The movable jaw14, has its operating end connected to the upper end of a rod 25, andthe lower end of this rod is connected with a crank 11, which is rigidlysecured to the outer end of the rod 16. Y

The upright bar 2, has a shaft 7, journaled therein, the outer end ofthe said shaft carrying a sprocket wheel S around which the sprocketchain 6, passes. Placed around the inner end of the shaft 7, is a collaror tube 26, which vcarries a rigid jaw 9, and this jaw 9, coacts with ajaw 10, secured to the inner end of said shaft 7. From this constructionit will be seen that as the shaft 7, is revolved the jaw 10, isbroughtin contact with thejaw 9, of the collar and the collar caused torevolve with the shaft, and the two jaws made to clasp one end of thematerial which is to be formed into a band, the other end of the saidmaterial being held between the jaws 13 and 14. of the upright standard5. The rst wisp oftstraw is placed in the twisting jaws, after which asufficient quantity of straw is `grasped as it moves up the endlessapronv of a harvester to be deposited intothe cradle.

A wheel 16 carrying a crank pinis rigidly secured to the outer end of ahollow tube 16, the inner end of the said hollow tube carrying afriction disk 17, which engages the adjacent friction disk of thedriving shaft. By this means the said drivingshaftcauses the said wheel16 to revolve and through the medium ofa pitman rod 15, whichisconnected with the lower end of the uprightstandard 2, the twisterframe is reciprocated back and forth upon the hollow shaft q. Thetwister frame having its upper end inclined outward is in a position tograsp the straw or grain stems near their ends in the clamps of thetwister. The driving shaft is then moved endwise by any suitablemechanism,or by hand, to cause the friction disk thereof to engage thefriction disk of the hollow shaft 16,and thereby cause it to berevolved. The revolution of this shaft through the medium ofthe crankrod 15, draws the lowerend of the said twister frame outward, causing itto rise at the same time, owing to the contact of the cog wheels Vs,with the inclined rack t, and the wheel u at the opposite end with theinclined track Iv. As the lower end of the said twister frame is carriedoutward the cog wheel s, is revolved by contact with the said inclinedrack, thus communicatinga revolution to the said hollow shaft q. Thisshaft in turn causes the twister at the upper end of the upright 2, torevolve through the mediumv of the sprocket wheel l, and sprocketchainl6, as will be clearlyunderstood. At the same time the rod 16, ismoved outward so that the straw is twisted and lengthened out at thesame time. The material being twisted into a band is supported by atrough 28, and as the lower end of the twister frame is moved outwardthe outer end of the lever 18, is also drawn outward through the mediumof a connecting rod 13', whichhas its opposite end connected with theshaft r. The opposite end of this lever 18, is

provided with a series of cogs which engage with a cog wheel 19, andthis cog wheel 19, in turn engages the cog Wheel l?` upon the lower endof the vertical cradle supporting shaft.

y inwardly extending projection at the lower i In Fig. 1, the machine isshown in position to be operated, with the upper end of the twisterframe inclined backward and the cradle frame extending transverse themachine. As the upper end of the twister frame moves forward, as justdescribed, twisting and lengthening the' band, the cradle is turnedone-quarter around through the medium ofv the rod 13', lever 18, and thecog wheel 19, as just setforth. By this means the cradle frame isbrought around at right angles tov that shown in Fig. l, so that thecompressor arms are in a position to have the twisted band placedbetween the forks ot their ends'atter which the straw to be formedinbundles falls therein from an elevator inthe usual manner. This beingdone, the twister frame through the medium of the mechanism justdescribed, isdrawn in the opposite direction, thus turning the cradleframe back tothe position shown in Fig. l. The driving shaft isthenmoved endwise in the opposite direction and this throws into operationthe binding mechanism. The iirst movement is the closing of thecompressor arms around the bundle which is piaced in the cradle framethrough the medium of the endwise sliding collar which is upon the shaftsupporting the said cradle frame. This is elected through the medium ofthe lever M which is operated by the slotted wheei J already described.

As shown in Fig; 1,` the upper end of the crane is outside of the outerside of the cradle frame and this is carried back to its proper positionthrough the medium ot the dog which is upon the shaft Y. This dogengages the end of the crane and brings the crane around over thecradle. v

I will now describe what I term the tucker.

At the outer end of 'the pivoted arm m', forming the upper portion ofthe crane is piv oted a depending tucker lip 29, which is held normallyoutward by means of a spring 30, placed within the outer end of the saidarm m', and engaging the inner face of the said depending lip. This lipis provided with a pivoted latch 31, which has its free end supported bya staple 32. Just inside of the inner end of this latch 3l, is a triggerfor tripping the said latch out of engagement with the staple whichsupports and engages the should er thereof. The lower end ot thistrigger engages the inner endl of the said latch and the upper end ofthe trigger extends slightly above vthe swinging arm m. Projectingoutward from they upper edge of the said swinging arm m is an arm 33,which has a depending tucker lip 34. VPivoted in the lower end of thisouter tucker lip is a bar 35,'

which carries a tncker 36. To both ends of this bar are attached cranks37, to which is attached a bail 38. A chain or cord has one end attachedto the inner end of this bail and its opposite end attached' to the drumatthe lower end of ythe crane. The cranebeing in the position shown inFig. l, is swung around as above stated by the dog upon the shaft Y,

and in swinging around the ends ot theband which are held by the forksof 'the compression arm are guided between the tucker lips by means ofthe wire guides 42, which are at the lower ends of the tucker lips. Thecrane being in this position with the projecting ends of the bandbetween the tucker lip, the single cog h engages the pinion at the lowerend of the crane, thus revolving the drum and drawing upon the chainwhich is connected with the bail of the tucker. This causes the upperend of the bail to be drawn inward and as the bail moves inward itengages the upper end of the trigger thus causing the lower end of thetrigger to raise the inner end of the latch ot' the inner lip of thetucker. This releases the tucker lip allowing the springl to force itoutward and to thus grasp the extending ends oi the said band. Thecontinued revolution of the shaft Y brings 'the cogs of the segmentalwheels V around into engagement with the pinion upon the lower end ofthe cradle supporting shaft, thus revolving the cradle while the ends ofthe twisted band are being held, thus twisting the ends of the twistedband around. When the revolving of the cradle is most nished the seriesof cogs g of the wheel engage the pinion at the lower end of the cranecausing a tighter draw upon the chain connected with the bail thusdrawing it inward farther and throwing inward and downward the tucker36, which tucks the ends of the band, forces the' lip 29 inward untilheld by the latch 3l thus releasing the ends of band and raises thepivoted arm 'm'. `The tuclrer 36 coming in contact with the lip 29forcesv the latter inward, thus releasing the ends of the band. Thecontinued inward movement of the bail causes the tucker36 to forcethelatch 3l in engagement with the staple 32, at the same time that itraises the arm m'. This being done the arm t', of the wheel j', engagesthe extended shaft j, thus throwing the upper end of the crane outward,the swinging arm m', having been previously raised by the drawing uponthe chain which is attached to the said bail. The shaft Y will then havemade a' revolution thus bringing the wheel J around in proper positionto permit the compressor arm to move outward owing to the lever Mallowing the collar upon the cradle shaft to move downward. Thiscompleting the binding operation the Ydriving shaft is again movedendwise which brings into operation the twisting mechanism which againtwists the material placed in the trough and turns the cradle around asbefore described, to receivethe twisted band, and then the hindingoperation is carried on in the manner as above described.

As shown, one of the twisters at the upper end of the twisting frame isconstructed to have its outer end engage the material being twistedwhile the other twister or clasp is adapted to hold at its inner end.The object IOO of this is, the straw being twisted is allowed an endwisemovement one stem upon the other as one end of the ktwister frame movesoutward in the manner heretofore described. In this way the straw orother material held by the clasp is twisted and at the same timelengthened endwise, as will be readily understood.
